What are the tempers of aluminum alloys?

According to different processing methods, the temper of aluminum alloy processing products can be summarized as follows:

  • H: Work hardening temper. It is applicable to products that improve strength through work hardening. After work hardening, the product can undergo (or not) additional heat treatment to reduce the strength.aluminum alloy
  • O: Annealed condition. It is applicable to the processed products with the lowest strength after complete annealing.
  • T: Heat treatment temper. It is applicable to products with (or without) work hardening to reach stability after heat treatment. There must be one or more Arabic numerals after the code T (Generally, it is heat treatment strengthened material).aluminum alloy
  • W: Solution heat treatment temper. It is a kind of unstable temper. It is only applicable to alloys naturally aged at room temperature after solution heat treatment. This tempers code only indicates that the product is in the natural aging stage.
  • F: Free machining temper. It is applicable to products without special requirements for work hardening and heat treatment conditions during the forming process. The mechanical properties of products in this temper are not specified.aluminum alloy
